Check Digit Verification of cas no

The CAS Registry Mumber 1415730-50-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,5,7,3 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1415730-50:
(9*1)+(8*4)+(7*1)+(6*5)+(5*7)+(4*3)+(3*0)+(2*5)+(1*0)=135
135 % 10 = 5
So 1415730-50-5 is a valid CAS Registry Number.

Synthesis of 6 H-Benzo[ c]chromene Scaffolds from O-Benzylated Phenols through a C-H Sulfenylation/Radical Cyclization Sequence

Karreman, Steve,Karnbrock, Simon B. H.,Kolle, Sebastian,Golz, Christopher,Alcarazo, Manuel

, p. 1991 - 1995 (2021)

S-Aryl dibenzothiophenium salts, obtained through a highly regioselective C-H sulfenylation of o-benzyl-protected phenols, are used as precursors of 6H-benzo[c]chromenes. The reaction starts with a photocatalytically triggered single-electron transfer to the sulfonium salt, which promotes the formation of an aryl radical via selective mesolitic cleavage of the S-Arexo bond. Mechanistic studies reveal that this initial radical species cyclizes following a kinetically favored 5-exo-trig pathway. Subsequent ring expansion, favored by rearomatization, delivers the desired tricyclic systems.
